2821 and a HWIC-4ESW=

I have a 2821 with a HWIC-4ESW= installed int slot 0. I cannot see the FastEthernet interfaces in my NAT list.
Specifically I have a a 1300 series AP in my defauly VLAN (1) and I cannot ping it when I have it connected to f0/1/1. I have f0/1/1 configured in trunk mode (for grins I have tried both). I can ping my 1300 when I plug it in to a Catalys Express 500 with the port configured via smartports as an access point with a native VLAN of 1.
To me it seems that the HWIC-4ESW= is not configured correctly in the 2821 or the 2821 is not allowng the fastethernet interfaces to talk to the gigabitethernet interfaces. Any thoughts?
Thanks,
Mike

I do not have an IP address on the VLAN 1 interface. I do have an IP address on the same subnet on interface g0/0.1 - 10.1.l.254/24 in vlan1.
The device on f0/1/1 is 10.1.1.55/24 also in vlan1.
Can I have the g0/0 segmented in to sub-interfaces and still brige it to a hwic-4esw port?
I could make the 1300 series bridge that connects to the hwic-4esw (f0/1/1) part of a different vlan, but would like to have the APs in the managment vlan along w/ the switches and router.
Thanks,
Mike

Presales: HWIC-4ESW= on 2821 to increase Ethernet port?

Hi there,
I was not able to receive help from Cisco partner and distributor so I'm hoping that I'll get response from here.
We have CISCO2821-V3PN/K9 whose two Gigabit ports are already used. I need additional Ethernet port to connect the router to the Internet Leased Line.
Below "appears to be" the right product but the module is a switch which to my understanding is meant for connecting to the inside LAN rather than to the Internet.
HWIC-4ESW= Four port 10/100 Ethernet switch interface card
Grateful if someone could shed some light and give me the right product (part no.) we need to buy.
Thanks in advance.

Hello Archie,
a configuration for a VLAN on your 2821 would look like this:
interface Vlan2
ip address 192.168.1.1 255.255.255.0
You can assign that VLAN, 2 in this case, to one of the switchports, just like you would assign it to a ´normal´, or better, external switch:
interface FastEthernte0/1/0
switchport access vlan 2
Here is a link that provides information regarding VLANs in conjunction with the HWIC:

How to enable routing between HWIC-4ESW and Onboard FE on cisco 1841 router..?

Hello All,
I have a cisco 1841 router, recently i have purchased HWIC-4ESW slot for my router. The module is working fine i could able to see additional FE ports(fe0/0/0,fe0/0/1...).Now problem comes in routing i.e. these HWIC-4ESW ports and Onboard FEs are not communicating.If any bode knows the solution kindly let me know the configuration details..
Thanks,Sazz

Re: Difference between HWIC-1FE and HWIC-4ESW

Hi
I am trying to find out the main difference between the HWIC-1FE and HWIC-4ESW cards.
Also I have a cisco 2811 router that is configured with one Fastethernet connected to DSL and the other port connects to mt LAN and METRO (using subinterfaces), is this the best practice?

HWIC-4ESW is the 4-port single-wide 10/100BaseT Ethernet switch HWIC. The 4ESW is a L2 switch and is cost effective.
HWIC-1FE is 1-port Fast Ethernet HWIC. The HWIC-1FE is a true L3 interface and is expensive. It has feature parity with an onboard FE interface except for OAM support, which is delayed.
HWIC-4ESW has the capability to setup VLAN but they are not the routed ports Whereas, HWIC-1FE has the same characteristics as Onboard FE ports.

HWIC-4ESW

folks
i have a 2821 ISR with a HWIC-4ESW installed and a firewall running ospf on the end of one of the switch ports
the switchport is assigned to a vlan and the vlan interface has an ip
my problem
the switchport is layer 2 and won't see the firewall, i can't even see a mac-address! the line is up as is the protocol so figure its a config problem
i've tried setting the firewall interface in the same vlan number - no joy
i need ospf to run between the firewall and the router - has anyone any idea of what i can do
i think there's a compatibility problem with the HWIC-4ESW and may need another L3 card - can i get one for the 2821?
thanks to anyone taking the time to reply

This should have no problem communicating. Can you try to provide the following:
1. show diag
2. show run int fa x/x >> the switchport connecting to the firewal.
3. sho run inter vlan x >> the vlan created for the port connecting to the firewall.
4. Is the interface vlan up/up? You mentioned the l2 port but was the interface vlan up/up?
Did you try pinging from 2821 to the firewall's interface ip address, the interface connecting to the L2 port.

I am trying to get NAT working on a Cisco 2801 with HWIC-4ESW.

I have a 2801 that had a failed Fe0/1 port. The Fe0/1 port was used to give sub-interface Fe0/0.200 access to internet. We installed a HWIC-4ESW into the 2801. I have successfully moved the sub-interfaces ( 0/0.1 , 0/0.100 , and 0/0.200 ) from the Fe0/0 to the HWIC-4ESW. I have reconfigured the Fe0/0 to connect to my ISP. However, I cannot get traffic from vlan200 to pass to the internet over Fe0/0. I have a guest wireless network set for vlan 200. Clients get an IP address in the appropriate range (192.168.200.0), but they cannot get to the internet. Below I have included the results of "sh ip int brief" and some of the "sh run". I think that it is something simple, but I canot get it working.
Help would be appreciated.

HWIC-4ESW having same MAC address with fa0/0 from CISCO2811 router.

Hi Expert, I Have a situation where a 2811 is configured with 2 VLANs from HWIC-4ESW module, different ports configured, however the VLAN interfaces have the same mac-address with fa0/0 which causes ARP poisoning problem. It that anyway to solve this problem?

Hi Lee,
My understanding is, this is expected behavior and is due to the hardware limitation of the HWIC-4ESW Module. And I think the HWIC-4ESW Module (at least from my lab testing) always takes the MAC Address of the first on board LAN Interface.
Also, I am able to change the MAC Address of the first on board LAN Interface (Ex.Gig0/0) but I cannot change the MAC Address of the VLAN SVI.
I hope it helps.

Arul

HWIC-4ESW routing

What are the routing capabilities of the HWIC-4ESW?
Can i configure a different IP subnet in each port?

Hi,
The following link gives full configuration guidelines for the HWIC-4ESW:
http://www.cisco.com/en/US/products/sw/iosswrel/ps5207/products_feature_guide09186a00802c6bb6.html
In answer to your question, yes - you can have a different IP subnet in each port. (And if it's a trunk you can have multiple IP subnets per port)

Hwic 4esw monitor Session

Currently running a hwic 4esw module in a 2800 series router and we are using websense so I’m trying to use Monitor session to mirror the traffic over for websense to see. The only problem is that the route locks up every week and doesn’t allow any traffic out. Any ideas?

I need some clarifications from your side to help you out with the problem.Are you able to normally ping the Websense server from the PIX? .When the problem occurs are you able to ping the websense server from the PIX?. Is the PIX reachable from the rest of the network when the problem occurs?
Send me these details so that I can help you further.

Is the HWIC-4ESW card supported in the WAE-674-K9?

Hi,
In the datasheet of the WAE-674-K9 says that it supports (4-port network interface card (NIC) for inline Cisco WAAS deployment), but don't mention the HWIC-4ESW anywhere. Is it supported?
Any help is much appreciated!

Hi,
The WAE-674-K9 support 4 port NIC for Inline Deployment and the card is WAE-INLN-4CG.

2801 with TWO HWIC-4ESW-POE

Hi,
2801 with AC-IP power, PVDM2-8 (c2801-advipservicesk9-mz.124-7a.bin) is being used at branch office.
They have four slots:
slot0: vic2-2fxo (for local call, 911, srst)
slot1: HWIC-4ESW-POE (IP Phones)
slot2: WIC-1DSU-T1-V2 (T1 internet)
slot3: HWIC-4ESW-POE (IP Phones)
The router recongize all the modules, but some reason, the IP phones wont register to CCM. PC wont get IP address from local DHCP pool from router itself.
It only happens at slot3, slot1 is working fine.
My questions are that: is 2801 support TWO HWIC-4ESW-POE at slot 1 and slot 3 at the same time?? If it does support, any reason why.
Thanks for help...
Ken

Ken, Are the phones in slot 3 powering up ?
are they in same vlan as slot 1 phones ? If you swap phones between slot 3 and slot 1, do the phones that were originally in slot3 do register , get an ip etc..?
It looks like two hwics esw are supported in 2801, the question is whether two hwics with poe are supported or not. If you get power on both slots for the phones, the router is definitely granting power to all 8 ports.
http://www.cisco.com/en/US/products/ps5855/products_qanda_item0900aecd8016c026.shtml
Also does the port show connected on slot 3?
Also try removing slot 1 hwic and see if slot3 phones do get registered.

Fan Part Numbers for Cisco 2801, 2821 and 2851 fans

I have P/Ns for Cisco 2811 router fans as follows:
ACS-2811-FAN-1/2= and ACS-2811-FAN-3=
But I do not have part numbers for fans used in 2801, 2821 and 2851 routers.
Does anyone have these prt numbers?
It doesn't make sense to change the whole router for just a fan failure.

Hi
for the 2821 and 2851 routers the fan is the same : ACS-2821-51-FANS=
for 2801 the whole chassis needs to be replaced

Nm-1CE1T1-PRI on 2821 and 2811

Hi
How many NM-1ce1t1-pri modules can be installed on cisco 2821 and 2811 ?

There is only one NM slot on the 2811 and 2821 so you can only fit one NM-1CE1T1-PRI.
Hope this helps.

Terminate IPsec on one of the ports of HWIC-4ESW (through VLAN)

Hi,
It's not clear to me whether it's possible to terminate IPSec on one of the ports of HWIC-4ESW (through VLAN)? The document on the link below suggests that it supports L3 with limitations but it's short in mentioning whether IPsec is one of the limitations.
